FAQ

Frequently
Asked Questions.

Need a question answered that isn't here? Send your pipe specifications and target capacity directly to our engineering team for a tailored response.

What is pipe cladding?
Pipe cladding is the process of depositing overlay welding material onto a pipe surface to protect it against wear, abrasion, corrosion, and impact damage -- forming a metallurgical bond between the deposit and the base pipe.
What can this pipe cladding machine weld?
The machine is primarily used for pipe overlay welding, performing cladding on pipe inner walls, outer walls, and shaft surfaces of cylindrical components.
What pipe sizes are supported?
The standard configuration supports workpiece diameter from φ100 mm to φ600 mm and length up to 2,000 mm. Custom configurations for larger ranges are available on request.
Which welder is used?
The standard configuration uses a Shanghai Hugong NB-630 gas-shielded welder or Aotai. According to customer requirements, it can be customized to inverter welder or submerged-arc welder configurations.
What is the difference between cladding and lining?
Lining typically forms a mechanical bond used for protection or repair. Cladding produces a metallurgical bond between the overlay material and the pipe surface -- delivering superior wear life and bond integrity under heavy-duty service conditions.
